In https://webrtc-review.googlesource.com/c/src/+/1560 we moved WebRTC from src/webrtc to src/ (in order to preserve an healthy git history). This CL takes care of fixing header guards, #include paths, etc...

// objects which would then be passed to VideoSendStream. Eventually,
|

// direct accessors like packet_router() should be removed.

|
// WebrtcSession. Video and audio always uses different transport

// objects, even in the common case where they are bundled over the

|
// same underlying transport.

|

// Extracting the logic of the webrtc::Transport from BaseChannel and

// subclasses into a separate class seems to be a prerequesite for
